' BRAKE-BEAM FOR ELECTRIC AND OTHER CARS.

Specification of Letters Patent. Applicstinii filed 111M125, 1906.Serial No. 813,683.

Patented bet. 9,1900.

To; all whom it may concern:

Be it known that I, SE'rii A. (.uoun, a citizenof the United States, anda resident of New York cit in the county of New Yorkcw York, haveinvented cer- 5 and State of tain new and useful lm rovenicnts inBrakelleams for Electric an other (Burs, of which the following is nspecification.

' The invention relates to improvcmcnts in I brake-beams for electric:md other curs; run:

' it consists in the novel fcu turcs and construction hereinafterdescribed, and particularly pointed out in the claims. 1

Brn ke-bcamsof the class to which my ini vcntion .pcrtains comprise itrolled bod ybeam of suitable length, brake-heads of suitablc'construction on the ends thereof, and a fulcrum for the brake-lever; andmy invcn tion has for-its object-to produce a novel fulcrum for use insuch beams, said fulcrum being capable of Bel firmly and quickly appliedto thohcijlmwnr -of sustaining, the great strains.

T to which fulcrums in modern high-speed clac- ,,.tric ours aresubjected, the, fulcrum of my in- Wcntion being of forged metal bentinto the desired shape, the parts of the fulcrum while beingjgivcn suchshape not being unduly stretched or weakened. The fulcrum of myinvention comprises side members to receive between them thebrake-lover, flanges to lap around the flange of the body-beam, andflanges laterally spread apart to engage the web of the'body-beu-m, saidweh-flangos being out of vertical alincment with cach other and theentire fulcrum being preferably, though not necessarily, formed of oneintegral bar of forged metal or one integral merchant-bar. It is usuallynecessary in modern clcctricscar equipment that the sides of the fulcrumstand at right angles to the longitudinal line of tho body-heam, and inaccordanccwith my in- "l ention I am enabled to give these sides suchmile and secure the spreading apart of the Iwe -fianges without undulyweakening or punishing the metal while giving it tho proper outlines tosecure an efficient fulcrum, tho production of which is the object of myinwvention.

The invention will be fully understood from ;o the detailed descriptionhereinafter present ed, reference being had to the accompanyingdrawings, in which Figure 1 is a detached to view of n. fulcrumconstructed in accor once with and 55 embodying the invention. Fig. 2 isanouter end view of sdme, taken from the right-hand end of Fig. l cndindicating by dotted lines a. portion of the body-beam. Fi 3 is atransverse section through a. brakeearn-having the fulcrum appliedthereto, the fulcrum ,being shown in side elevation; and Fig'..4 is a.detached face view, partly broken sway, of a. bar of forged metal whichI utilize in'the production of the fulcrum shown'injFig l-fi 1 In thedrawings, 10 designates a portionof the usual body-bea'm,jand 11 thenovel fulj-C. crum of my invention, which is appliedcen trally on 'onedge. ofi-thclbeani 'nnd inpthe '5 form shownis oneintegmlgbarfo"forgcdgf metal folded, at its ccut'er g toji fdrm til members 12 133,which areape 11 14,, to receive the pin. for thoflbrak cveninot shown)and standat a'right ang c-to the on gitudinal line of the beam l0,:,a 'nd at'th 3 nor ends of which sides thc cn the bar have a twist olffnpnfiqfi opposite directionsifninrsn 'si'd curved flanges,linibfgphe,

The flanges 17 extend inwardly transversely of the bod -beamnnd substantially at, right angles to the longitudinal line thereof,while,

as shown in Fig. 1, the flnngosglS flare outwardly in a direction andfrom thcinner edges of said'flain'gsu'; -;Thc flanges 18 are, as shownin Fi I and-2, set

.outwiirdly beyond the vcrtica planos-fof thc.

sides 12 13,,and said flanges 18 are secured to the web of the body-beambyrivets 19. 9 5 I run enabled to form the fulcrum in the spccinloutline shown and sbovc' described without unduly stretchin or weakeningthc metal in. the for; ration 0% the flangesl5 by making it from a brgedhair 20, Fl 4, having Ioc its cud portions rcversoly. dispose in theoutline shown in Fig. 4, eacl'i of said end portions comprising alatcrally-dcllcctod section 21 and an outr-r section 22, which is at. anangle to the bodx of the bar 20 and inclines'reversely 05 at an angle tothe section 21. The sections 2-] 22 may he formed on the ends of the bar.20 by means oi dies in a press, said dies bending the bar on its ed asto produce said sections. I indicate in lg. 4 as closely as pos 1 losihle by dotted lings 23 24, respectively, the

lines on which the 'reversely-disposed cud portions of the bar will bebent to form the flanges 17 18, the dotted lines 23 denoting the line ofthe fold of the bar at the horizontal outer edge of the beam-flange 16and-the dotted lines 241 'denotin theline of the fold of the bar at theadjoining edges of .the flanges 17 18. A portion of the sections 21 ofthe bar is utilized in the formation of the flanges 15, and anotherportion of said sections is utilized in the formation of the flanges 18,while that portion of said sections 21 intermediate the lines 23 24finally forms the flanges 17. In the production of the fulcrum from thebar 20 the latter is first reversely bent on edge at its ends to producethe reversqgections 21 22, then each end'of the bar is bent to form thefian 'cs 15 l7 l8, and finallv the bar is folded at its middle toproduce the sides 12 13.

Iprefer to form the entirefulcrum in one integral piece from amerchant-bar on ac count of the manifest su )eriority of the integralstructure; but it is-o vious that with less advantage the fulcrum sidesmay be in se 'arate pieces, and, if desired, riveted togct er at theouter end 25 of the fulcrum in the severa. ways l rnown to the art-as,for illustration; as shown in Patent No. 720,677, dated February 17,"1903.

dln-accprdance with my present invention I am enab ed to produce afulcrum from forged metal and" without unduly stretchin or weakening thesame, having sides w 'ch stand at right angles to the length of thebody-befiin,-'fiiid are .provided at their inner ends with flan es 15;17, and 18 to engage said bedm, the flanges 18 bein spread apart, sothat they extend outwan ly from each other and beyond and at rightangles to the. vertical lanes of said sides.

W'hat claim as niv invention, and desire to secure by Letters atent, isv 1. A brake-beam fulcrum of forged bar metal having vertical sidemembers 12 15, flanges l5 curving therefrom to the horizontal edges ofthe beam-flange, and flanges 17, 18 respectively engaging saidbearndlange and the web of the beam, said flanges 18 being extendedoutwardly in a direction from each other and at right angles from saidside mombers; substantiall as set forth.

2. A brake-beam fulcrum in one inte'ral piece of forged bar metal foldedat its middle portion am having vertical side members 12, 13, flanges 15curving therefrom to the horizontal edges of the beam-flange, andflanges 17, 18 respectively engaging said beam-flange and the web of thebeam, said flanges 18 being extended outwardly in a direction from eachother and at right, angles from said side members; substantiullx' as setforth.

3. A brake-beam fulcrum of forged bar metal comprising side members toreceive the brake-lever and having at their inner ends the flanges 15curving therefrom to the hori zontal edges of thebeam-flange and flanges17, 18 respectively engaging said beam-flange and the web of the beam.said flanges 18 be in g extended outwardly in a direction from andbeyond each other, and said side members having at their inner ends thelaterally revei-sely disposed end portions for the formation of sahlflangcs and each comprising a laterally-deilccted inner section 21 andan outer rcversely-deflooted section 22 dis osed at an angle to thebodyofthe bar and a so to said section 21 substantially as set forth.

4. A brake-beam fulcrum in one inte ral piece of forgired bar metalfolded at its middle portion anr com-prising side members to receive thebrake-lever and having attheir inner ends the flan cs 15 curvingtherefrom to the horizontal e ges of the beam-flange and flanges 17, 18respectively engaging said beam-flan e and the web of the beam, saidflanges 18 eing extended outwardly in a direction from and beyond eachother, and said side members having at their inner ends the laterallyrcverselv dis oscd end portions or the formation of sail flanges andeach comprising a laterally-deflected inner section .31 and an outerreverscly deflected section 22 disposed at an angle to the body of theher and also to said section 21; substantially as set forth.
